GRAPHA-Holding AG CH-6052 HergiswilGRAPHA Holding AG CH-6052 Hergiswil Rotierend antreibbares SchneidwerkzeugRotating cutting tool

Die Erfindung betrifft ein rotierend antreibbares Schneidwerkzeug gemäss Oberbegriff des j^aj^ntanspruches 1.The invention relates to a rotary-driven cutting tool according to the preamble of claim 1.

Ein solches Schneidwerkzeug vermittelt die DE - B - 37 19 721, bei dem der Messerträger an der von der Schneidebene abgewendeten Rückseite durch eine schräg nach aussen abfallende Ringfläche ausgebildet ist, an welcher die Schneidmesser in Führungsnuten hinsichtlich der Schneidebene verschieb- und feststellbar angeordnet sind, wobei das Feststellen der Schneidmesser durch Schrauben erfolgt, die einen Schlitz des Messerschaftes durchsetzen und mit dem Kopf an letzterem anliegen. Die Schneidkraft wird zum Teil von den Schrauben als Biege- und Scherkräfte aufgenommen und der Schaft des Schneidmessers ist durch den Schlitz erheblich geschwächt -eine an sich unzulängliche Bauweise.Such a cutting tool is described in DE - B - 37 19 721, in which the knife carrier is formed on the rear side facing away from the cutting plane by an annular surface sloping outwards, on which the cutting knives are arranged in guide grooves so that they can be moved and locked in relation to the cutting plane, whereby the cutting knives are locked in place by screws that pass through a slot in the knife shaft and rest against the latter with their heads. The cutting force is partly absorbed by the screws as bending and shearing forces and the shaft of the cutting knife is considerably weakened by the slot - an inadequate design in itself.

Aufgabe der vorliegenden Erfindung ist es, ein Schneidwerkzeug der eingangs genannten Art zu schaffen, bei dem die erwähnten Nachteile behoben sind, die Führungsnuten geschont werden und das einen schnelleren Messerwechsel gestattet.The object of the present invention is to create a cutting tool of the type mentioned at the beginning, in which the disadvantages mentioned are eliminated, the guide grooves are protected and which allows a faster blade change.

Erfindungsgemäss wird diese Aufgabe nach den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst. Der Einspannquerschnitt des Schaftes bleibt unverändert konstant. According to the invention, this object is achieved according to the characterizing features of patent claim 1. The clamping cross-section of the shaft remains unchanged and constant.

Anschliessend wird die Erfindung unter Bezugnahme auf die Zeichnung, auf die bezüglich aller in der Beschreibung nicht näher erwähnten Einzelheiten ausdrücklich verwiesen wird, anhand eines Ausführungsbeispiels erläutert. In der Zeichnung zeigen:The invention is then explained using an exemplary embodiment with reference to the drawing, to which reference is expressly made for all details not mentioned in detail in the description. In the drawing:

Fig. 1 eine stirnseitige Ansicht eines Schneidwerkzeuges undFig. 1 is a front view of a cutting tool and

Fig. 2 einen Querschnitt des Schneidwerkzeuges nach der Linie II - II in Fig. 1.Fig. 2 shows a cross section of the cutting tool along the line II - II in Fig. 1.

In den Fig. 1 und 2 ist ein rotierend antreibbares Schneidwerkzeug 1 zum Beschneiden von ein- oder mehrblättrigen Druckprodukten oder Materialbahnen dargestellt, das aus einem kreisförmigen Messerträger 2 besteht, dessen Nabe 3 an einer Antriebswelle eines Getriebes (nicht ersichtlich) lösbar befestigt werden kann. Diesbezüglich sind dafür Schraubendurchgangslöcher 4 vorgesehen. Von der Nabe 3 erstreckt sich in radialer Richtung an den Umfang des Messerträgers 2 eine kegelige Oberfläche, an welcher auf den Umfang verteilt radial verlaufende, vor der Nabe 3 endende Führungsnuten 5 vorgesehen sind.Figures 1 and 2 show a rotary-driven cutting tool 1 for trimming single- or multi-sheet printed products or material webs, which consists of a circular blade carrier 2, the hub 3 of which can be detachably attached to a drive shaft of a gear (not visible). Screw through holes 4 are provided for this purpose. A conical surface extends from the hub 3 in the radial direction to the circumference of the blade carrier 2, on which guide grooves 5 are provided that run radially and end in front of the hub 3.

Jeweils ein Paar der Führungsnuten 5 bildet mit einer dazwischen liegenden Klemmplatte 6 eine Aufspannanordnung für die in den Führungsnuten 5 verschiebbaren Schneidmesser 7, die an ihrem Schaft 8 festklemmt werden.Each pair of guide grooves 5 forms, with a clamping plate 6 in between, a clamping arrangement for the cutting blades 7 which can be moved in the guide grooves 5 and which are clamped to their shaft 8.

Der Schaft 8 der Schneidmesser 7 besitzt einen trapezförmigen Querschnitt, sodass er in die schwalbenschwanzförmige Füh-The shaft 8 of the cutting blades 7 has a trapezoidal cross-section so that it fits into the dovetail-shaped guide

— 3 ——3—

rungsnut 5 längsverschiebbar passt.groove 5 fits longitudinally displaceably.

Die Schneidmesserenden 9 überstehen den Umfang des Messerträgers 2 und bilden eine zur Rotationsachse 10 des Schneidwerkzeuges 1 senkrecht verlaufende Schneidebene 11, die vor der Stirnseite des Messerträgers 2 liegt.The cutting blade ends 9 protrude beyond the circumference of the blade carrier 2 and form a cutting plane 11 that runs perpendicular to the rotation axis 10 of the cutting tool 1 and lies in front of the front side of the blade carrier 2.

Die Klemmplatte 6 ist aufgrund der hier in einem spitzen Winkel angeordneten Führungsnuten 5 oder Schneidmesser 7 mit gleichem Winkel trapezförmig ausgebildet und durch eine Befestigungsvorrichtung mit dem Messerträger 2 durch zwei Schrauben verbunden. Die sich zur Rotationsachse 10 hin verjüngende Klemmplatte 6 liegt mit den schrägen Trapezflächen an den ihr zugewendeten geneigten Komplementärflächen der Schäfte 8 zweier Schneidmesser 7 an und presst diese bei festgezogenen Schrauben in die Führungsnuten 5. Der zwischen den Schäften 8 der Schneidmesser 7 und Führungsnuten 5 dadurch entstehende Reibungsschluss verhindert eine Überbeanspruchung der Spannschrauben in der Klemmplatte 6.The clamping plate 6 is trapezoidal in shape due to the guide grooves 5 or cutting blades 7 arranged at an acute angle and is connected to the blade carrier 2 by means of a fastening device using two screws. The clamping plate 6, which tapers towards the rotation axis 10, rests with its inclined trapezoidal surfaces on the inclined complementary surfaces of the shafts 8 of two cutting blades 7 facing it and presses them into the guide grooves 5 when the screws are tightened. The frictional connection that is created between the shafts 8 of the cutting blades 7 and the guide grooves 5 prevents the clamping screws in the clamping plate 6 from being overstressed.

Die Befestigungsvorrichtung der Klemmplatte 6 ist in der Zeichnung durch eine Ausnehmung 12 ausgebildet, deren Grundfläche eine bündige Fläche mit den benachbarten Führungsnuten 5 bildet.The fastening device of the clamping plate 6 is formed in the drawing by a recess 12, the base of which forms a flush surface with the adjacent guide grooves 5.

Sofern die Schäfte 8 der Schneidmesser 7 in ausreichender Höhe die Führungsnuten 5 überragen, könnte auf die Ausnehmung 12 zwischen zwei Führungsnuten 5 verzichtet werden. Die Ausnehmungen 12, die die Führungsnuten 5 jeweils einseitig unterbrechen, begünstigen jedoch eine vorteilhafte schmale Querschnittsform im Umfangsbereich des Messerträgers 2.If the shafts 8 of the cutting blades 7 protrude sufficiently above the guide grooves 5, the recess 12 between two guide grooves 5 could be dispensed with. The recesses 12, which interrupt the guide grooves 5 on one side, however, promote an advantageous narrow cross-sectional shape in the peripheral area of the blade carrier 2.
